Figure 3.
Multiple DnaJ isoforms interact with AR and ARv7.
(A) Lysate from HEK293 cells transfected with FLAG-ARv7 or FLAG-AR was probed with FLAG-beads. Bound proteins were detected by WB.
(B) Lysate from HEK293 cells cotransfected with indicated FLAG-DnaJ family members and GFP-AR or GFP-ARv7 was probed with FLAG-beads. Bound proteins were detected by WB. Red arrow notes detection of native FLAG-DnaJC5, which tends to oligomerize. AR antibody N-20 was used to detect FL-AR and ARv7.
(C) Lysate from 22Rv1 CRPC cells transfected with indicated FLAG-DnaJ family members was incubated with FLAG-beads. Bound proteins were detected by WB. Red arrow notes detection of native FLAG-DnaJC5, which tends to oligomerize.
Experiments were repeated at least three times.
